Amazon delivery guy picked up my return, but refund/replacement still not showing

Hey everyone,
I ordered two lights — one 21m and two 60m. But I received two 21m lights and only one 60m. I raised a return using the 60m light’s order (since both were delivered under one order but picked up together). The delivery guy already collected the full package, but now Amazon shows that the replacement order got cancelled — and it still doesn’t show as “cancelled” or “refunded” in my account. Customer care told me to cancel the order and i would be able to get the refund but i am not sure this will happen, they said it’s cancelled from their side, but there’s no update on refund yet. What should I do next? Anyone faced something similar
